/** @example moduleExample_Mod.cpp 
 * @brief Example demonstrating how to implement a module with ArModule
 *
  This is a simple example of how to define a module of code that Aria's ArModuleLoader class can dynamically load at runtime.
  On Windows, loadable modules are DLL files. On Linux, they are shared object (.so)
  files (ARIA's Makefiles can compile any source file ending in "Mod.cpp" into
  a .so, so to build this module, run "make moduleExample_Mod.so").
  ArModuleLoader knows about these platform conventions, so only the base name
  (without the .dll or .so suffix) is used to load it.
  To implement a loadable module, you derive a class from ArModule,
  instantiate the pure virtual functions init() and exit(), and create an
  instance of that class. The two functions simply print out the equivalent
  of Hello World. An important part is the global instance of the class
  and the call to the macro ARDEF_MODULE(). Without that macro invocation,
  Aria will never be able to invoke those two functions.

  The program moduleExample.cpp is designed to load this module and check the
  error return.
